图像Mosaics技术综述

A Survey of Image Mosaics Technology

本文系统综述了当前图像Mosaics技术的研究现状.图像Mosaics技术就是将一组重叠图像拼结成一幅大型的无缝高分辨率图像的技术.我们根据图像Mosaics形成的二维曲面即流形(Manifold)的确定方式将图像Mosaics技术分为两大类:基于自适应流形的图像Mosaics和基于人工确定流形的图像Mosaics基于自适应流形的图像Mosaics是由视频序列提取的条形图产生的.基于人工确定流形的图像Mosaics是由整幅图像的拼接对齐所产生的.它包括局部对齐技术、全局对齐优化调整技术和图像融合技术.我们对每种技术进行了分类和讨论.最后给出了评价并展望了未来图像Mosaics技术的发展方向.

The paper surveys image mosaics technology. Image mosaics are the technologies that a large, seamless and high-resolution image is made from a set of images. The paper calls the 2-D surface formed by the image mosaics as the manifold. According to the mode how the manifold is formed,it divides the image mosaics into two kinds:adaptive manifold-based image mosaics and man-selected manifold based one. Adaptive manifold-based image mosaics are produced by the strips from video. Man-indicated manifold-based image mosaics are made from image alignment. It includes local alignment, global alignments and image blend. The paper classifies and discusses the above technologies. At last,it gives an evaluation and discusses the future development of image mosaics.
